there is a reason why you all had issues with those words.. if misspelled while mainly in the proper order, sometimes the reading gets interrupted because we come across a word that we don't know :D
as for important (apart of our mind not knowing that extra 'h') the 'e' instead of an 'a' actually made my mind read impotent rather important lol... apparently the 'e' took precedence over 'r' despite impotent not making full sense in the statement; a typo is a typo regardless how our minds formulate words i guess ^^
